The compound is useful as agricultural fungicides, insecticides and miticides. There are also disclosed a process for producing the above compound and agricultural fungicidal, insecticidal and miticidal compositions.

FIELD OF THE INVENTION

The present invention relates to novel aminopyrimidine derivatives useful as agricultural fungicides, insecticides and miticides, and also relates to their production and use.

BACKGROUND OF THE INVENTION

Certain kinds of aminopyrimidine derivatives, especially 4-aminopyrimidine derivatives, are known to have insecticidal activity, miticidal activity and fungicidal activity (JP-A 57-176967, JP-A 63-225364 and JP-A 64-68362).

However, these known aminopyrimidine derivatives do not have satisfactory efficacy, particularly with regard to fungicidal activity. There is still a need for compounds having more potent fungicidal activity.

OBJECTS OF THE INVENTION

The main object of the present invention is to provide novel aminopyrimidine derivatives having potent fungicidal activity as well as insecticidal and miticidal activity.

Another object of the present invention is to provide a process for producing aminopyrimidine derivatives.

Yet another object of the present invention is to provide novel intermediate compounds for the production of the aminopyrimidine derivatives.

Still another object of the present invention is to provide agricultural fungicides, insecticides and miticides containing the above aminopyrimidine derivative.

These objects as well as other objects and advantages of the present invention will become apparent to those skilled in the art from the following description.

Reference Example 1

Synthesis of 4-(2-(tetrahydropyran-2-yloxy)ethyl)bromobenzene

p-Toluenesulfonic acid (0.30 g) was added to a solution of 4-bromophenethyl alcohol (9.50 g, 47.24 mmol) in methylene chloride (50 ml), and the mixture was stirred under ice-cooling. To the mixture was added 3,4-dihydropyran (5.53 g, 65.74 mmol). After stirring under ice-cooling for 20 minutes, a saturated aqueous solution of sodium bicarbonate (40 ml) was added to the reaction mixture. The resulting mixture was extracted with methylene chloride and dried over magnesium sulfate. After evaporation of the solvent, the desired 4-(2-(tetrahydropyran-2-yloxy)ethyl)bromobenzene was obtained (13.40 g, 99%).

Reference Example 2

Synthesis of 4-(2-(tetrahydropyran-2-yloxy)ethyl)phenethyl alcohol

Magnesium (1.31 g, 53.90 mmol) was added to a solution of 4-(2-(tetrahydropyran-2-yloxy)ethyl)bromobenzene (14.00 g, 49.09 mmol) in tetrahydrofuran (20 ml). Then dibromoethane (0.1 ml) was added under an atmosphere of nitrogen gas, and the mixture was stirred under room temperature for 1 hour. After cooling to ice-cooling temperature, 2M-ethylene oxide/tetrahydrofuran solution (49.09 ml, 98.18 mmol) was added, and the mixture was stirred at room temperature for 2 hours. Then, water (40 ml) was added to the reaction mixture. The mixture was extracted with ethyl ether and dried over magnesium sulfate. After evaporation of the solvent, the residue was purified by column chromatography on silica gel eluting with n-hexane/ethyl acetate (=8/2) to give the desired 4-(2-(tetrahydropyran-2-yloxy)ethyl)phenethyl alcohol (6.00 g, 42%).

Reference Example 3

Synthesis of 4-(2-(tetrahydropyran-2-yloxy)ethyl)phenethyl methanesulfonate

Triethylamine (3.22 g, 31.82 mmol) was added to a solution of 4-(2-(tetrahydropyran-2-yloxy)ethyl)phenethyl alcohol (4.00 g, 15.97 mmol) in methylene chloride (40 ml). The mixture was stirred under ice-cooling, and methanesulfonyl chloride (2.19 g, 19.11 mmol) was added dropwise to the mixture. After the addition, the resulting mixture was stirred under ice-cooling for 10 minutes. Then, water (40 ml) was added. The mixture was extracted with methylene chloride and dried over magnesium sulfate. Evaporation of the solvent gave the desired 4-(2-(tetrahydropyran-2-yloxy)ethyl)phenethyl methanesulfonate (5.24 g, 99%).

Experimental Method

In experiments for determination of preventive effect, a liquid sample to be tested was sprayed to test plants. After 24 hours, pathogens were inoculated. In experiments for determination of therapeutic effect, the test plants were inoculated with each pathogen. After 48 hours, a liquid sample to be tested was sprayed to the test plants. The liquid sample was prepared by dissolving the test compound in a small amount of N,N-dimethylformamide and diluting the solution with distilled water containing a spreader to a given concentration.

Controlling effect on cucumber powdery mildew (Sphaerotheca fuliginea)

Seeds of cucumber (var.: TSUKUBASHIROIBO; 1.3 to 1.8 leaf stage) were sown in plastic cups (each 9 cm in diameter), followed by cultivation for 2 to 3 weeks. A liquid test sample adjusted to 2.0 ppm was sprayed on the surface of their first leaves. The pathogen was inoculated by spraying to the leaves a conidia suspension of Sphaerotheca fuliginea which had been cultured on the cucumber leaves.

Insecticidal Activity of the Compound of the Invention

The following test examples show experiments for evaluating insecticidal activity of the compound of the invention against three kinds of injurious insects. The test solution was prepared by dissolving the compound to be tested in a small amount of N,N-dimethylformamide and diluting the solution to a given concentration with distilled water containing a surfactant.

Test Example 3

Insecticidal activity against green peach aphid (myzus persicae)

A piece of a Chinese cabbage leaf with a diameter of 3 cm was put, with the back up, on a 0.3% agar gel. Apterous adults were inoculated on it, and kept at 25° C. for 1 day. Then born larvae were counted. Then the adults were removed. A given concentration of the test solution was sprayed on the larvae on the piece of the Chinese cabbage leaf. After 48 hours at 25° C., the dead larvae were counted, and the ratio of the dead insects (i.e., larvae) to the above born larvae was calculated to evaluate the effect. The results are shown in Table 62.

Test Example 4

Insecticidal activity against green rice leafhopper (Nephotettix cincticeps)

Six to seven paddy seedlings were bound into sheaves, and stem part of the bundle was covered with sponge. The seedlings were fixed in a polyethylene cup with a diameter of 6 cm containing a small amount of water at the bottom part by the sponge, and covered with a cylinder of stainless steel screen mesh. Then ten female adults were released in the cylinder. A given concentration of the test solution was sprayed thereto. After 48 hours at 25° C., the dead insects were counted, and the ratio of the dead insects to the above ten insects was calculated to evaluate the effect. The results are shown in Table 62.

Test Example 5

Miticidal activity against two spotted spider mite (Tetranychus urticae)

Ten female adults of Tetranychus urticae (sensitive population breeded successively using kidney bean leaves) were inoculated on a leaf of kidney bean seedlings in a cup. The test solution diluted to a given concentration was sprayed, and the kidney beans were kept in a glasshouse. The compounds which prevented damage by the mites after 12 days were evaluated as having the activity.

The results are shown in Table 62 in terms of the percent control at 63 ppm.
